Starscopes on azimuthal mount

A lot of interesting celestial objects are wai-
ting to be viewed by you. A detailed listing 
would go beyond the scope of this guide. 
There is very good literature on this subject 
in our online store and, of course, a lot of free 
information on the Internet and astronomy fo-
rums. Nevertheless, here are a few examples, 
which are ideal especially for the beginner.

The Moon

The moon is the easiest and especially for 
beginners an extremely productive observati-
on object. It is easy to find and shows a lot of 
details even for the untrained eye. Especially 
interesting is the observation of the light-dark 
boundary, the so called „terminator“. 
There the sun casts long shadows, so that 
craters and mountains look especially vivid. 
At full moon no shadows can be seen, the 
moon then looks flat and overlit.

The planets

If you have some observing experience with 
the moon, the planets are the next interesting 
target. You can see especially much at Jupi-
ter and Saturn. Saturn‘s rings, for example, 
or even Jupiter‘s four brightest moons can be 
seen without much experience. 
With a little more practice you will be able to 
see many additional details, e.g. the cloud 
bands on Jupiter.
Venus (also known as the morning or evening 
star) already shows its phase shape even in 
small telescopes, similar to our moon.

Mercury, Mars and Uranus are also within 
reach of your telescope, but they show much 
less detail than the planets Jupiter and Saturn 
mentioned above. You should observe the 
planets during a so-called „opposition“, since 
they are closest to Earth then. 
Note: Not all planets are visible in the sky at 
all times. A celestial calendar tells you which 
planets are visible and when and where they 
can be discovered. 

Objects outside our solar system

There are also numerous objects which are 
within the range of your telescope.For the 
beginning the perhaps most interesting „Deep 
Sky Objects“. 
• the „Ring Nebula“ M57 in Lyra 
• the globular cluster M13 in Hercules 
•  the Andromeda Nebula M31, a huge galaxy 

at a distance of about 2.5 million light years 
(use as low magnification as possible). 

•  Open star clusters like the 

Pleiades

 in 

Taurus, 

h and xi

 in Perseus or 

M11

 in the 

constellation Scutum.
